A camera includes a motor, a planet gear mechanism having a planet gear to be revolved or rotated by the motor, a film wind mechanism provided on a revolution orbit of the planet gear and meshed with and driven by the planet gear upon forward rotation of the motor to perform film winding, a film rewind mechanism provided on the revolution orbit of the planet gear and meshed with and driven by the planet gear upon reverse rotation of the motor to perform film rewinding, a focal point switching mechanism provided on the revolution orbit of the planet gear and meshed with and driven by the planet gear upon reverse rotation of the motor to switch a focal length of a photographic lens, and a selecting mechanism for selectively causing the planet gear to mesh with the film rewind mechanism or the focal point switching mechanism upon reverse rotation of the motor.

A camera includes a camera body having a photographing mask, a cassette chamber on one side of the photographing mask and a film winding spool on the other side. A motor rotates the winding spool in a film winding direction and a spring pushes the film toward the photographing mask to thereby apply a predetermined load against movement of the film. A roller applies to the film a tensile force which is smaller than the predetermined load on the film winding side to maintain the film flat at the photographing mask.

A camera capable of changing over the photographing frame size thereof having a photographing frame size changing member disposed in a camera body and capable of moving between a first position at which the photographing frame size changing member partially covers a film exposing opening and a second position at which the changing member does not cover the film exposing opening; and an operation member disposed on a rear cover of the camera for selectively bringing the photographing frame size changing member to the first position or the second position, wherein the changing member and the operation member are non-mechanically connected to each other in a state where the film is interposed between the changing member and the operation member. In another embodiment flexible changing members, being positively driven, are guided from a position behind the film to a position in front of the film exposing opening. Visual and/or audible indicators are provided to alert an operator as to the photographing frame size.

A camera with a lens mount having an imaging lens and a barrier which is disposed on a camera body and which is shiftable between a closed position where the barrier covers a part of the lens mount and the entire front of the imaging lens and an open position where the barrier is clear of the front of the lens mount. When the barrier is at the closed position, the barrier allows the front of the lens mount to be partly exposed. The camera thus constructed achieves a minimum dimension in the width across the camera body including the barrier.

A picture-format switchable camera having a picture-format setting device for setting a picture format, and a picture-format switching device for switching to the picture format set by the picture-format setting device from another picture format. The picture-format switching device is disposed between the aperture of a camera body and the light-sensitive surface of a film.

A camera having a photographing mask, a cassette chamber on one side of the photographing mask and a film winding spool on the other side includes: a motor for rotating the winding spool in a film winding direction; a spring disposed between the cassette chamber and the photographing mask, the spring having a first spring unit for pushing a film cassette, toward an inner wall of the cassette chamber to thereby position the cassette, and a second spring unit for pushing the film, drawn from the film cassette, toward the photographing mask to thereby apply a predetermined load against movement of the film; and a device for applying to the film a tensile force which is smaller than the predetermined load on the film winding side. Thus, it is possible to dispense with an independent pressure plate.

An apparatus for X-ray CT imaging including an X-ray irradiation unit configured to irradiate an X-ray toward a subject, an X-ray detector having a plurality of X-ray detection elements along a channel direction and a row direction, a couch on which the subject can be arranged, a rotation unit on which the X-ray irradiation unit and the X-ray detector are oppositely disposed and rotate around the couch, a controller configured to execute a helical scan while fluctuating an X-ray focal spot along a body axis direction of the subject by controlling the X-ray irradiation unit, and an image processing unit configured to generate a reconstructed image based on data acquired by the helical scan, wherein the controller is further configured to set a magnitude of fluctuation of the X-ray focal spot so that data acquisition loci of the helical scan do not overlap each other.

A casing of a motor with resolver includes a stator, a motor shaft rotatably supported by a bearing, a motor rotor integrally rotatable with the motor shaft, and a resolver for detecting a rotation angle of the motor rotor. The resolver includes a disc-shaped resolver stator held on the motor casing and having a surface on which a thin-film-shaped coil is formed, and a disc-shaped resolver rotor provided on an end face of the motor rotor and having a surface on which a thin-film-shaped coil is formed. Part of the motor casing holding the outer periphery of the resolver stator is formed as a shield portion cylindrically protruding along the outer periphery of the resolver rotor to the rotor. The motor casing and the shield portion are each made of a non-magnetic conductive material.
